“However, keep in mind that the third transverse mode also has an antinode at the center of the bar.”

“A region where the variation of a quantity has a relative maximum is called an antinode of that quantity.”

“The distance from an antinode to a node is that from 1-2 on the curve and is one-fourth a wave length.”

“If two of the three indices are zero, then the pressure antinodes of the associated mode form planes.”

“Very similar to a coffee cup, whose nodes and antinodes are determined by the location of the handle.”

“As the speaker volume increases, the difference between nodes and antinodes becomes easier to hear.”
